At least one of two furniture items ( 101 ) adjacent to each other includes an elastically deformable cushion portion ( 102   c ) on an outer surface thereof facing the other of the two furniture items ( 101 ) adjacent to each other. The connection plate ( 200 ) includes connection portions ( 201, 205 ) which are connected to each of furniture items ( 101 ) on both end portions of the connection plate, and the connection portion ( 201 ) of at least a first end portion of the connection plate ( 200 ) can engage with and disengage from the furniture items ( 101 ) in a state where the cushion portion ( 102   c ) is compressively deformed in a direction in which the two furniture items ( 101 ) adjacent to each other approach each other, and an engagement state of the connection portion ( 201 ) with respect to the furniture items ( 101 ) is maintained in a state where the compressively deformed cushion portion ( 102   c ) is deformed in a direction in which the cushion portion returns to the original shape.

TECHNICAL FIELD

The present invention relates to a furniture system which includes multiple furniture items such as sofas.

Priority is claimed on Japanese Patent Application No. 2014-017383, filed Jan. 31, 2014, the content of which is incorporated herein by reference.

BACKGROUND ART

Multiple furniture items such as sofas may be arranged and installed on a floor (for example, refer to Patent Document 1). In addition, in a case where a table or a cabinet is installed so as to be adjacent to sofas or the like, furniture items of multiple kinds may be arranged and installed.

For example, in a case of a sofa, the surface of the sofa is covered with a soft cushion. If a user sits on the sofa, the cushion is deformed such that it bulges outside when the cushion is pressed from the upper portion thereof. Accordingly, in a case where other sofas or furniture items are installed to be adjacent to the sofa without a gap therebetween, the adjacent other sofas or furniture items are pressed in a longitudinal direction by the outwardly bulged cushion, and the positions thereof may deviate.

Therefore, a method is used, in which a plate is provided on the lower surface of a sitting portion of a sofa, and the sofa and other sofas or furniture items are connected to each other by bolt-tightening a connection metal fitting to the plate.

In addition, Patent Document 1 discloses a configuration in which a belt-shaped connection member is provided on one sofa, and a connected member to which the connection member is locked is provided on another sofa.

CITATION LIST Patent Literature

[Patent Document 1] Japanese Unexamined Patent Application, First Publication No. 2013-94405

SUMMARY OF INVENTION Technical Problem

However, bolt-tightening the connection metal fitting takes much labor.

In addition, in a furniture item such as a sofa, there may not be a sufficient gap below the lower surface of the sitting portion, and it may be difficult to bolt-tighten the connection metal fitting to the lower surface of the sitting portion. If a furniture item such as a sofa is dropped down sideways or is vertically inverted, a bolt-fastening operation is easily performed. However, in a case where the furniture item is heavy or the furniture item may be damaged if the furniture item is vertically inverted, it may be difficult to make the furniture item drop down sideways or to vertically invert the furniture item.

In addition, in the case where the connection member is locked to the connected member like in Patent Document 1, when the positions of the sofas have deviated, the locking between the connection member and the connected member may be released.

Accordingly, an object of the present invention is to provide a furniture system in which furniture items may be connected easily and reliably and positional deviation of the furniture items is prevented.

Solution to Problem

The present invention adopts the following means in order to solve the above-described problems.

According to an aspect of the present invention, a furniture system includes: multiple furniture items which are disposed to be adjacent to each other; and a connection member which connects the multiple furniture items to each other, in which at least one of two furniture items adjacent to each other includes an elastically deformable cushion portion on an outer surface thereof facing the other of the two furniture items adjacent to each other, the connection member includes connection portions which are connected to each of the furniture items on both end portions of the connection member, and the connection portion of at least a first end portion of the connection member can engage with and disengage from the furniture items in a state where the cushion portion is compressively deformed in a direction in which the two furniture items adjacent to each other approach each other, and an engagement state of the connection portion with respect to the furniture items is maintained in a state where the compressively deformed cushion portion is deformed in a direction in which the cushion portion returns to the original shape.

In the furniture system, in order to connect the two furniture items adjacent to each other with the connection member, the two furniture items adjacent to each other are pressed in a direction in which the two furniture items approach each other and the cushion portion is compressively deformed. Accordingly, the connection portion of at least a first end portion of the connection member can engage with the furniture item.

In this way, after the connection portion of the connection member engages with the furniture item, pressing between the furniture items is released. Therefore, the compressively deformed cushion portion is deformed in the direction in which the cushion portion returns to the original shape. As a result, the engagement state of the connection portion with respect to the furniture items is maintained. Accordingly, the two furniture items are connected to each other.

In addition, in order to release the connection between the two furniture items, the two furniture items adjacent to each other are pressed in a direction in which the two furniture items approach each other and the cushion portion is compressively deformed. Accordingly, the connection portion of at least the first end portion of the connection member can be disengaged from one of the furniture item.

In this way, it is possible to connect the furniture items to each other without performing a bolt fastening operation.

In addition, an engagement member with which the connection member engages may be provided on one of the furniture items adjacent to each other, the connection portion may include an insertion portion into which the engagement member is inserted in a state where the cushion portion is compressively deformed in the direction in which the two furniture items adjacent to each other approach each other, and an engagement portion which is formed to be continuous to the insertion portion, is open with respect to the insertion portion in a direction in which the furniture items are separated from each other, and engages with the engagement member.

According to this configuration, the engagement member can be inserted into the insertion portion in the state where the cushion portion is compressively deformed in the direction in which the two furniture items adjacent to each other approach each other. Accordingly, the connection member can engage with and disengage from one of the furniture item.

Moreover, if the compressively deformed cushion portion is deformed in the direction in which the cushion portion returns to the original shape, the engagement member engages with the engagement portion, which is open in the direction in which the furniture items are separated from each other, rather than with the insertion portion. Accordingly, the engagement state of the connection member with respect to one of the furniture items is maintained.

In addition, a second end portion of the connection member may be rotatably connected to the other of the furniture items which is adjacent thereof.

According to this configuration, it is possible to connect the two furniture items adjacent to each other by rotating the connection member.

In addition, in a state where the connection between the furniture items is released, since the connection member is connected to the other of the two furniture items which is adjacent thereof, it is not necessary to prepare a separate connection member.

The engagement member may include a displacement allowance portion which engages with the furniture item in a state where the connection member can be displaced in a height direction of the furniture item.

According to this configuration, even in a case where the height levels of the furniture items adjacent to each other are different from each other due to unevenness of a floor surface, it is possible to connect the furniture items to each other with the connection member.

The furniture item may include a furniture main body, and a leg portion by which the furniture main body stands on a floor surface, and the connection member may be disposed on a lower surface of the furniture main body.

According to this configuration, a gap exists between the lower portion of the furniture main body supported by the leg portion and the floor surface. Therefore, the connection operation of the furniture items with the connection member can be easily performed by allowing a hand to enter the gap between the furniture main body and the floor surface.

The connection member may be disposed on a base portion of the leg portion.

Accordingly, it is possible to cause the furniture items adjacent to each other to approach each other by gripping the leg portions of both furniture items. Therefore, it is possible to easily perform the connection operation between the furniture items with the connection member.

At least one of the furniture items adjacent to each other may be a sofa.

Accordingly, it is possible to easily and reliably connect a sofa in which the outer surface has the cushion portion to other sofas or other furniture items.

Advantageous Effects of Invention

According to the furniture system of the present invention, it is possible to easily and reliably connect furniture items to each other and prevent positional deviation of the furniture items.

The panel body 11 is formed in a flat plate shape, an approximate L shape in which an intermediate portion is bent or curved when viewed in a plan view or in a side view, an approximate C shape in a plan view in which the entirety is curved, or the like according to the shape of an installed appliance or the like. Hereinafter, a case where the panel body 11 is formed in a flat plate shape is described.

(Panel Base Material)

The panel base material 12 includes a panel-shaped core material 15, a frame 20 which is provided along the outer circumferential portion of the core material 15, and a base sheet 18 which is provided so as to cover both surfaces of the core material 15 and the frame 20.

For example, the core material 15 is formed of a paper based material, a resin base material, a wood based material, or the like. Preferably, the core material 15 is as lightweight as possible. Accordingly, in the present embodiment, the core material 15 is formed of a paper based material, multiple holes 15 h penetrating the core material 15 in a plate thickness direction are disposed in parallel, and for example, the core material 15 has a honeycomb structure in which multiple holes 15 h having hexagonal cross-sections are combined in a staggered manner.

(Frame)

As shown in FIGS. 4 and 5, the frame 20 is provided on the outer circumferential portion of the core material 15. The frame 20 includes frame materials 21A, 21B, 21C, and 21D which are provided along four sides of the core material 15. Each of the frame materials 21A, 21B, 21C, and 21D is formed of a metal based material, a resin based material, or the like.

The frame materials 21A and 21B extend in a vertical direction along two sides facing each other in the core material 15 and are provided on both sides in the width direction of the panel body 11. The frame materials 21C and 21D extends in a horizontal direction so as to be orthogonal to the frame materials 21A and 21B and are provided on both sides in the vertical direction of the panel body 11. The frame materials 21A and 21B and the frame materials 21C and 21D are joined to each other via L-shaped brackets 22 by bolts 23, welding, bonding, or the like. The frame 20 having a rectangular shape as a whole is formed by the frame materials 21A, 21B, 21C, and 21D.

As shown in FIGS. 6 to 8, each of the frame materials 21A, 21B, 21C, and 21D is formed in an approximately U-shaped cross-section which includes a base portion 21 e which faces an outer circumferential end surface 15 a of the inner circumferential side core material 15 of the frame 20, and side wall portions 21 f which rises from both sides in the width direction of the base portion 21 e toward the outer circumferential side of the frame 20. Accordingly, a groove 25 is formed in a portion which is surrounded by the base portion 21 e, and both side wall portions 21 f and 21 f.

Meanwhile, the panel base material 12 is continuous along the outer circumferential end portion thereof, and includes the groove 25 which is recessed toward the inner portion of the panel base material 12.

Here, as shown in FIG. 5, in the L-shaped bracket 22, a first plate portion 22 a which is provided on the end portion of the frame material 21A or 21B along the frame material 21A or 21B, a second plate portion 22 b which is orthogonal to the first plate portion 22 a and is provided on the end portion of the frame material 21C or 21D along the frame material 21C or 21D, and a rib portion 22 c which is provided on the inside in the bending direction of the L-shaped bracket 22 along the first plate portion 22 a and the second plate portion 22 b are integrally formed.

Female screw portions 29 are formed on the first plate portion 22 a and the second plate portion 22 b of the L-shaped bracket 22. In addition, through holes 28 are formed on each of the base portion 21 e of the frame material 21A or 21B along the first plate portion 22 a of the bracket 22 and the base portion 21 e of the frame material 21C or 21D along the second plate portion 22 b at positions facing the female screw portions 29. The female screw portions 29 and the through holes 28 are optional member attachment portions which attach various optional members exemplified below.

The rib portion 22 c is orthogonal to the first plate portion 22 a and the second plate portion 22 b from the first plate portion 22 a and the second plate portion 22 b and is formed so as to protrude toward the inner circumferential side of the panel body 11. The rib portions 22 c is formed on each of both sides in the width direction of the first plate portion 22 a and the second plate portion 22 b, that is, each of a first surface side and a second surface side of the panel body 11.

The rib portion 22 c functions as not only a reinforced member which increases bending strength of the first plate portion 22 a and the second plate portion 22 b but also functions as a pressing member of corners of the core material 15. Accordingly, the core material 15 is interposed between the rib portions 22 c which are provided on the first surface side and the second surface side of the panel base material 12. That is, in the panel base material 12, the core material 15 can be held inside the frame 20 by providing the brackets 22 on the four corners.

As shown in FIGS. 7 and 8, the sheet-shaped base sheets 18 are provided on both surfaces of the core material 15 so as to cover the frame 20 and the core material 15. For example, the base sheet 18 is formed of cardboard or the like. External dimensions of the base sheet 18 are greater than those of the core material 15, and the outer circumferential portion 18 a of the base sheet 18 is bonded to the surface 20 f of the frame 20 by a bonding agent or the like.

(Cushion Material)

The cushion material 13 is provided along the base sheet 18 which forms the surface of the panel base material 12. The cushion material 13 is provided so as to the entire core material 15 via the base sheet 18. In addition, the cushion material 13 is provided such that an outer circumferential end portion 13 s of the cushion material 13 covers a side wall portion 21 f of each of the frame materials 21A, 21B, 21C, and 21D which configure the frame 20. That is, the cushion material 13 is provided so as to cover the core material 15 and the frame 20.

For example, the cushion material 13 is formed of a material having flexibility and elasticity such as a foamed urethane material.

FIGS. 9A and 9B are sectional views showing the cushion material 13 which is provided along the surface of the panel base material 12, FIG. 9A is a sectional view of the cushion material 13 in a state where a skin material 14 is not mounted, and FIG. 9B is a sectional view of a cushion material 13 in a state where the skin material 14 is mounted.

As shown in FIG. 4, multiple through holes 16 are formed in the cushion material 13. For example, each of the through holes 16 is formed in an elliptical shape which has a vertical direction as a longitudinal direction. In addition, the multiple through holes 16 are arranged on an outer surface 13 f of the cushion material 13 at intervals therebetween in the vertical direction and the horizontal direction orthogonal to the vertical direction.

As shown in FIGS. 7, 9A, and 9B, each through hole 16 is formed to penetrate the cushion material 13 in the thickness direction of the cushion material 13 from the outer surface 13 f facing the side opposite to the panel base material 12 in the cushion material 13 to an opposing surface 13 g facing the panel base material 12 side. As shown in FIG. 9A, each through hole 16 is formed such that an inner circumferential surface 16 f of the through hole 16 is orthogonal to the outer surface 13 f. Accordingly, corners 16 v are formed on the circumferential edges of the through holes 16.

By providing the cushion material 13 having the through holes 16 formed as described above on the surface of the panel base material 12, uneven shapes having the corners 16 v are formed on the surface of the panel base material 12.

(Skin Material)

As shown in FIGS. 7, 9A, and 9B, the skin material 14 is provided to cover the entire cushion material 13. The skin material 14 is bonded along the outer surface 13 f of the cushion material 13, the inner circumferential surface 16 f orthogonal to the outer surface 13 f in the through hole 16, and an exposed surface 18 f of the base sheet 18 exposed to the bottom portion of the through hole 16. In this way, since the skin material 14 is provided along the multiple through holes 16 formed in the cushion material 13, multiple elliptical (uneven portions) recess portions 17 are formed on the surface of the panel body 11. In addition, in each recess portion 17, the skin material 14 is bonded to the base sheet 18 which forms the surface of the panel base material 12 via the through hole 16.

Here, for example, the skin material 14 is formed of an elastically deformable material such as polyester, and covers the cushion material 13 and the panel base material 12 in an extended state. In the cushion material 13, the corner 16 v which protrudes toward the outside in the circumferential edge of the through hole 16 on the outer surface 13 f is pressed toward the inside by the skin material 14. Accordingly, the cushion material 13 is elastically deformed in a compression direction in the corner 16 v, and the corner 16 v of the through hole 16 has an arc-shaped cross section.

In addition, as shown in FIGS. 7 and 8, external dimensions of the cushion material 13 and the skin material 14 are greater than the external dimension of the panel base material 12. In addition, the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 wrap around the outer circumferential edge portion of the panel base material 12, that is, the side wall portion 21 f of each of the frame materials 21A, 21B, 21C, and 21D, and are rolled inside the groove 25. The cushion material 13 is compressed by the skin material 14 by the portion of the side wall portion 21 f of each of the frame materials 21A, 21B, 21C, and 21D wrapped around by the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14. Accordingly, the panel body 11 is formed such that the thickness thereof gradually decreases toward the outer circumferential end portion 11 s. In addition, the panel body 11 is roundly formed in an arc shape by the portion of the side wall portion 21 f of each of the frame materials 21A, 21B, 21C, and 21D wrapped around by the cushion material 13 and the skin material 14 in the outer circumferential end portion 11 s.

The cushion material 13 and the skin material 14 configure a skin structure.

(Fixing Member)

The fixing member 30 is fitted into the groove 25. The outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 rolled into the groove 25 are interposed between the inner circumferential surface of the groove 25 and the outer circumferential surface of the fixing member 30 by the fixing member 30. Accordingly, the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 are fixed to the side wall portion 21 f of the frame 20.

Here, as shown in FIG. 4, the fixing member 30 includes linear portion fixing members 30S which are disposed on linear portions 12S of the outer circumferential portion of the rectangular panel base material 12, and corner portion fixing members 30C which are disposed on corner portions 12C of the outer circumferential portion of the rectangular panel base material 12.

As shown in FIG. 7, each of the linear portion fixing members 30S includes side plate portions 31 and 31 in which sectional shapes thereof orthogonal to the direction in which the linear portion fixing member 30S is continuous are parallel to each other, and a connection plate portion 32 which integrally connects the side plate portions 31 and 31 to each other.

The outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 are interposed between the side wall portions 21 f configuring the groove 25 of the frame 20 by the side plate portions 31 and 31. Accordingly, the gap between the side plate portions 31 and 31 is formed to be smaller than the gap of the side wall portions 21 f and 21 f of the groove 25 by predetermined dimensions. The side plate portions 31 and 31 are formed such that distal end portions 31 a and 31 a come into contact with the base portion 21 e of the groove 25 when the linear portion fixing member 30S is fitted into the groove 25.

The connection plate portion 32 is formed to be offset in a direction of being further separated from the base portion 21 e of the groove 25 relative to the distal end portions 31 a and 31 a of the side plate portions 31 and 31. Accordingly, the linear portion fixing member 30S has an approximately H-shaped cross section formed by the side plate portions 31 and 31 and the connection plate portion 32. In addition, in a state where the linear portion fixing member 30S is fitted into the groove 25, a space S1 is formed in a portion which is surrounded by the distal end portions 31 a and 31 a sides of the side plate portions 31 and 31, the connection plate portion 32, and the base portion 21 e of the groove 25. The space S1 functions as an accommodation space which can accommodate surplus portions of the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 rolled into the groove 25, that is, distal end portions (not shown) rather than the portions which come into contact with the base portion 21 e of the frame 20 in the outer circumferential end portions 13 e and 14 e.

In addition, protrusions 33 and 33 are formed on sides facing the side wall portions 21 f and 21 f of the groove 25 in the side plate portions 31 and 31. The protrusions 33 and 33 are bitten into the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 which are interposed between the side plate portions 31 and 31 and the side wall portions 21 f and 21 f. Accordingly, the linear portion fixing member 30S prevents the cushion material 13 and the skin material 14 from being extracted from the groove 25.

In addition, in the side plate portions 31 and 31, protrusion pieces 34 and 34 which protrude inside from the side plate portions 31 and 31 are formed on sides further separated from the base portion 21 e of the groove 25 relative to the connection plate portion 32. In addition, a holding groove 35 is formed, which is surround by the protrusion pieces 34 and 34, the side plate portions 31 and 31, and the connection plate portion 32 and serves as an optional member attachment portion.

As shown in FIG. 5, the corner portion fixing member 30C which is disposed on the upper corner portion of the panel body 11 is formed in an approximately L shape which includes a first linear portion 38A which vertically extends, and a second linear portion 38B which is bent from the upper end of the first linear portion 38A and horizontally extends.

The first linear portion 38A is fitted into the groove 25 on the upper end portion of the frame material 21A or the frame material 21B which vertically extends. The second linear portion 38B is formed so as to be continuous from one end of the first linear portion 38A, and is fitted into the groove 25 on both end portions of the frame material 21C or the frame material 21D. In this way, the groove 25 is continuously formed on the upper surface and both side surfaces of the base material 21, and the corner portion fixing member 30C is provided on the portion in which the upper surface groove 25 and both side surface grooves 25 are continuous to each other.

As shown in FIG. 8, each of the first linear portion 38A and the second linear portion 38B includes side plate portions 36 and 36 in which sectional shapes thereof orthogonal to the directions in which the first and second linear portions 38A and 38B are continuous are parallel to each other, and a connection plate portion 37 which integrally connects the side plate portions 36 and 36 to each other.

The outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 are interposed between the side wall portions 21 f and 21 f configuring the groove 25 of the frame 20 by the side plate portions 36 and 36. Accordingly, the gap between the side plate portions 36 and 36 is formed to be smaller than the gap of the side wall portions 21 f and 21 f of the groove 25 by predetermined dimensions. The side plate portions 36 and 36 are formed such that distal end portions 36 a and 36 a come into contact with the base portion 21 e of the groove 25 when the corner portion fixing member 30C is fitted into the groove 25.

Herein, in the side plate portions 36 and 36, protrusion portions 36 t and 36 t are formed on the sides facing the side wall portions 21 f and 21 f of the groove 25. The outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 are interposed between the side plate portions 31 and 31 and the side wall portions 21 f and 21 f by the protrusion portions 36 t and 36 t.

The connection plate portion 37 is formed to be offset in a direction of being further separated from the base portion 21 e of the groove 25 relative to the distal end portions 36 a and 36 a of the side plate portions 36 and 36. Accordingly, the corner portion fixing member 30C has an approximately H-shaped cross section formed by the side plate portions 36 and 36 and the connection plate portion 37. In addition, in a state where the linear portion fixing member 30S is fitted into the groove 25, a space S2 is formed in a portion which is surrounded by the distal end portions 36 a and 36 a sides of the side plate portions 36 and 36, the connection plate portion 37, and the base portion 21 e of the groove 25. The space S2 functions as an accommodation space which can accommodate surplus portions of the outer circumferential end portions 13 e and 14 e of the cushion material 13 and the skin material 14 rolled into the groove 25, that is, distal end portions (not shown) rather than the portions which come into contact with the base portion 21 e of the frame 20 in the outer circumferential end portions 13 e and 14 e. In addition, here, the connection plate portion 37 is closer to the base portion 21 e in the linear portion fixing member 30S relative to the connection plate portion 32, and thus, the space S2 is formed to be smaller than the space S1.

As shown in FIG. 5, the corner portion fixing member 30C is fixed to the groove 25 by a corner cap 40. The corner cap 40 is formed in an approximately L shape which includes a first linear portion 41A, and a second linear portion 41B which is continuous to one end of the first linear portion 41A and extends so as to be orthogonal to the first linear portion 41A. As shown in FIG. 8, the first linear portion 41A and the second linear portion 41B are inserted into a portion between the side plate portions 36 and 36 with respect to the first linear portion 38A and the second linear portion 38B of the corner portion fixing member 30C, and come into contact with the connection plate portion 37.

In addition, as shown in FIG. 5, a protrusion piece 43 is formed on the lower end portion of the first linear portion 41A so as to protrude toward the lower portion. The protrusion piece 43 is inserted into the holding groove 35 (refer to FIG. 7) between the connection plate portion 32 and the protrusion piece 34 on the upper end portion of the linear portion fixing member 30S.

In addition, as shown in FIG. 5, a bolt insertion hole 44 into which a bolt 45 is inserted is formed on the second linear portion 41B. The corner cap 40, the corner portion fixing member 30C, the frame material 21C, and the second plate portion 22 b of the bracket 22 are integrally fastened to each other by the bolt 45 inserted into the bolt insertion hole 44.

(Support Leg Body)

As shown in FIG. 5, as described above, each support leg body 50 is provided on each corner portion of both end portions of the lower portion of the panel body 11. Since the support leg body 50 is in contact with a floor surface, the panel body 11 is erected on the floor surface.

The support leg body 50 integrally includes a lower support portion 51 which is accommodated in the groove 25 by a lower end portion 12P of the panel base material 12, a side support portion 52 which extends upward from the one end of the lower support portion 51 and is accommodated in the groove 25 by a side lower end portion 12Q of the panel base material 12, and a support leg portion 53 which further extends downward relative to the lower support portion 51.

The lower support portion 51 comes into contact with the base portion 21 e which forms the lower surface of the groove 25 on the lower end portion of the frame 20 and is fixed to the base portion 21 e. In addition, the side support portion 52 comes into contact with the base portion 21 e which forms the bottom surface of the groove 25 on the side end portion of the frame 20 and is fixed to the base portion 21 e.

Bolt insertion holes 54 into which bolts 48 are inserted are formed in the lower support portion 51 and the side support portion 52. The bolts 48 which are inserted into the bolt insertion holes 54 are screwed into the female screw portions 29 and the through holes 28. Accordingly, the support leg body 50 is fixed to the panel body 11.

The support leg portion 53 extends further downward relative to the lower support portion 51, and a height adjustment screw 49 can be screwed into the lower end portion of the support leg portion 53.

A through hole 172A is formed on the lock portion 172 of the appliance upper connection bracket 171.

A bolt 179, which is inserted from the through hole 172A, is screwed with a base portion 178 which is provided inside the holding groove 35 of the linear portion fixing member 30S fixed to the frame material 21A (or frame material 21B) of the panel body 11 and in which a female screw is formed. In this way, in a state where the appliance upper connection bracket 171 is attached to the panel body 11, the upper portion of the back rest plate 108 of the sofa 101 is interposed between the holding wall portion 175 and the front wall portion 177 of the appliance upper connection bracket 171.

At this time, the cushion material 13P of the side, on which the outer wall portion 174 of the appliance upper connection bracket 171 is disposed in the panel body 11, is pressed by the outer wall portion 174. Accordingly, the width dimension of the cushion material 13P of the side on which the appliance upper connection bracket 171 is disposed is smaller than the width dimension of the cushion material 13Q of the side on which the appliance upper connection bracket 171 is not disposed. In addition, the end portion of the cushion material 13Q is flush with the end surface of the outer wall portion 174 of the appliance upper connection bracket 171 which is disposed along the cushion material 13P.

As shown in FIGS. 3 and 13, the upper portion of the sofa 101 and the lower portion of the panel body 11 are connected to each other via the appliance lower connection bracket 181.

The appliance lower connection bracket 181 includes a support wall portion 182 which is fixed to the base plate 105 of the leg portion 103 attached to the lower surface of the seat surface portion 102 of the sofa 101 by the bolt (not shown), and a bending wall portion 183 which is bent downward from the end portion of the support wall portion 182. The appliance lower connection bracket 181 includes a vertical wall portion 184 which is bent from the end portion of the bending wall portion 183 and is disposed along the skin material 14 of the panel body 11, a lower wall portion 185 which is bent from the lower end of the vertical wall portion 184 and extends toward the bent panel body 11 side, and a lock portion 186 which extends upward from the end portion of the lower wall portion 185. A rib 186A, which has a width corresponding to the gap between the side plate portions 31 and 31 of the linear portion fixing member 30S of the lower end portion of the panel body 11, is formed on the lock portion 186.

The lock portion 186 of the appliance lower connection bracket 181 is inserted into the portion between the side plate portions 31 and 31 of the linear portion fixing member 30S of the lower end portion of the panel body 11 so as to be locked.

In this way, the panel body 11 is mounted to the rear of the back rest plate 108 via the appliance upper connection bracket 171 and the appliance lower connection bracket 181.

(Connection Between Sofas)

Next, in the above-described sofa system 100, in the sofas 101 and 101 adjacent to each other, all the leg portions 103 and 103, and all the panel bodies 11 and 11 of the sofas 101 are connected to each other according to the following manner.

(Connection Between Panel Body Lower Portions by Support Leg Bodies)

FIG. 14 is a perspective view showing an example of a connection structure in a support leg bodies 50 which are provided on corners of the lower portions of the panel bodies 11. FIG. 15 is a sectional view showing a connection structure of the lower portions of the panel bodies 11 and 11.

As shown in FIGS. 14 and 15, one end of a lower connection member 55 for connecting the panel body 11 and another panel body 11 disposed to be adjacent to the panel body can be locked to the support leg body 50. Accordingly, a bulged portion 56 which is bulged further downward relative to the lower support portion 51 is integrally formed in the support leg body 50.

In the bulged portion 56, a slit 57 into which one end of the plate-shaped lower connection member 55 can be inserted is formed on the intermediate portion of the support leg body 50 along the thickness direction of the panel body 11.

The slit 57 is open to the side surface 56 a and the lower surface 56 b on the side of the bulged portion 56 adjacent to another panel body 11.

As shown in FIG. 15, an insertion recess portion 57 a, into which a protrusion portion 58A of the lower connection member 55 described below is inserted, is formed on the upper portion of the slit 57 to be recessed upward. In addition, in the upper portion of the slit 57, a protrusion portion 57 b which is adjacent to the insertion recess portion 57 a and protrudes downward is formed on the side surface 56 a side of the bulged portion 56.

In addition, in the bulged portion 56, a locking hole 56 h for locking the lower connection member 55 inserted into the slit 57 is formed to penetrate the panel body 11 in the thickness direction of the panel body 11.

Through holes 55 h are formed on both end portions of the lower connection member 55. In addition, the protrusion portions 58A protruding upward are formed on both end portions of the lower connection member 55. Moreover, in the lower connection member 55, a center protrusion portion 58B protruding upward is formed between the protrusion portions 58A and 58A of both end portions. In addition, engagement recess portions 58C which is recessed downward are formed between the center protrusion portion 58B and both protrusion portions 58A.

In the protrusion portion 57 b and the engagement recess portion 58C, the side surface 56 a side of the bulged portion 56 and the center protrusion portion 58B side become vertical surfaces 57 f and 58 f which vertically extend, and the opposite sides becomes inclined surfaces 57 g and 58 g which are separated from the vertical surfaces 57 f and 58 f toward the upper portion. Accordingly, each of the protrusion portions 57 b and the engagement recess portions 58C has a taper shape in which the width dimension gradually decreases toward the lower portion.

By fitting the protrusion portions 57 b of the slits 57 into the engagement recess portions 58C, the lower connection member 55 and the support leg bodies 50 easily positioned in the direction in which the panel bodies 11 and 11 are adjacent to each other.

In order to connect the panel bodies 11 and 11 adjacent to each other, both end portions of the lower connection member 55 in which through holes 55 h are formed are inserted into the slits 57 of the support leg bodies 50. The protrusion portions 57 b of the support leg bodies 50 which are provided on both panel bodies 11 are fitted into the engagement recess portions 58C on both end portions of the lower connection member 55. Here, each of the protrusion portions 57 b and the engagement recess portions 58C has a taper shape in which the width dimension gradually decreases toward the lower portion. Accordingly, the protrusion portions 57 b are inserted into the engagement recess portions 58C, and thus, the lower connection member 55 and the support leg bodies 50 easily positioned in the direction in which the panel bodies 11 and 11 are adjacent to each other. Therefore, the through holes 55 h formed on both end portions of the lower connection member 55 communicate with the locking holes 56 h of the support leg bodies 50. Thus, the connection bolts 59 are inserted into the through holes 55 h and the locking holes 56 h so as to be fastened. Accordingly, the lower end portions of the panel bodies 11 and 11 are connected to each other by the lower connection member 55.

(Connection Between Panel Body Upper Portions)

FIG. 16 is a perspective view showing an example of the connection structure of the upper portions of the panel bodies 11 and 11.

As shown in FIG. 16, it is possible to connect the upper end portions of the panel bodies 11 and 11 adjacent to each other by an upper connection member 61 serving as an optional member.

Instead of the corner caps 40, the upper connection member 61 is attached to the corner portion fixing member 30C. Bolt insertion holes 62 are formed on both end portions 61 a and 61 a of the upper connection member 61.

In addition, a gap regulation portion 63 is formed so as to protrude downward on the lower surface side of an intermediate portion 61 b of the upper connection member 61, and the gap regulation portion 63 regulates the gap between the corner portion fixing members 30C and 30C disposed on the upper portions of the panel bodies 11 and 11 adjacent to each other. The gap regulation portion 63 is inserted into the portion between the corner portion fixing members 30C and 30C which are disposed on the upper portions of the panel bodies 11 and 11 adjacent to each other, and thus, it is possible to regulate the gap between the panel bodies 11 and 11.

In order to connect the upper end portions of the panel bodies 11 and 11 to each other with the upper connection member 61, the following manner is performed.

First, the upper connection member 61 is placed on the corner portion fixing members 30C and 30C which are disposed on the upper portions of the panel bodies 11 and 11 adjacent to each other. At this time, the lower surfaces of both end portions 61 a and 61 a of the upper connection member 61 are inserted into the portion between the side plate portions 36 and 36 with respect to the second linear portion 38B of the corner portion fixing member 30C, and come into contact with the connection plate portions 37. In addition, since the gap regulation portion 63 can be inserted into the portion between the corner portion fixing members 30C and 30C disposed on the upper portions of the panel bodies 11 and 11 adjacent to each other, it is possible to regulate the gap between the panel bodies 11 and 11. More specifically, since the connection plate portions 37 of the first linear portions 38A of the corner portion fixing members 30C come into contact with both side surfaces 63 a and 63 a of the gap regulation portion 63, it is possible to appropriately position the gap between the panel bodies 11 and 11. In this state, bolts 64 inserted into the bolt insertion holes 62 are fastened to the female screw portions 29 through the through holes 28, and thus, the upper connection member 61, the corner portion fixing members 30C, the frame material 21C (refer to FIG. 5), and the second plate portions 22 b (refer to FIG. 5) of the bracket 22 are integrally fixed. Accordingly, the upper end portions of the panel bodies 11 and 11 adjacent to each other are connected to each other.

(Connection Between Leg Portions on Front Portion of Sofa)

FIG. 17 is a front view showing a connection portion of the leg portions 103 and 103 on the front portions of the sofas 101 and 101 adjacent to each other. FIG. 18 is a plane view showing a connection plate 200.

FIG. 19 is a side view showing an engagement member 210. FIGS. 20A and 20B is a view showing a flow when the leg portions 103 and 103 of the sofas 101 and 101 adjacent to each other are connected to each other, FIG. 20A is a view showing a state before the connection plate 200 is rotated, and FIG. 20B is a view showing a state immediately before a connection portion 201 of the connection plate 200 engages with the engagement member 210. FIG. 21 is a view showing a state where the connection portion 201 of the connection plate 200 engages with the engagement member 210 so as to connect the sofas 101 and 101 to each other.

As shown in FIG. 17, in the soft system 100, in the sofas 101 and 101 adjacent to each other, the leg portions 103 and 103 provided on the front end sides of the seat surface portions 102 are connected to each other by the connection plate 200.

As shown in FIG. 18, the connection plate 200 is formed of an elliptical metal plate.

The connection plate 200 includes the connection portion 201 and a connection hole (connection portion) 205 serving as connection portions connected to the sofas 101 on both end portions of the connection plate 200. The connection portion 201 is formed on the first end portion of the connection plate 200 and is connected to one sofa 101. The connection hole 205 is formed to penetrate the connection plate 200 on the second end portion of the connection plate 200, and is rotatably connected to the other sofa 101.

The connection portion 201 includes an insertion portion 202 which is open to a side 200 s extending in the longitudinal direction of the connection plate 200, and an engagement portion 203 which is formed so as to be continuous to the insertion portion 202.

The insertion portion 202 has an opening width which is greater than an outer diameter of a shaft portion 210 c (refer to FIG. 17) described below of the engagement member 210. The insertion portion 202 extends along a lateral direction of the connection plate 200 from the side 200 s of the connection plate 200.

The engagement portion 203 is formed in the intermediate portion in the lateral direction of the connection plate 200. The engagement portion 203 has an inner diameter which is greater than the shaft portion 210 c of the engagement member 210. The engagement portion 203 is formed so as to be offset toward the side separated from the connection hole 205 with respect to the insertion portion 202. Accordingly, in the engagement portion 203, an engagement recess portion 203 a is formed, which is enlarged toward the side separated from the connection hole 205 with respect to the insertion portion 202.

As shown in FIG. 17, by fastening a screw 206 penetrating the connection hole 205 to the base plate 105 of the leg portion 103, the connection plate 200 is rotatable in the inner surface along the lower surface 102 f of the seat surface portion 102 with the screw 206 as a center.

The engagement member 210 which engages with the connection plate 200 is provided on one of the sofas 101 adjacent to each other. As shown in FIG. 19, the engagement member 210 is a so-called stepped screw, and includes a screw head portion 210 a which is provided on a first end side, a male screw portion 210 b which is provided on a second end side, and a shaft portion 210 c which is formed between the screw head portion 210 a and the male screw portion 210 b and has an grater outer diameter than that of the male screw portion 210 b.

As shown in FIG. 17, in the engagement member 210, the male screw portion 210 b is screwed into the base plate 105 of the leg portion 103 which is provided on the lower surface of the seat surface portion 102 of the sofa 101. Accordingly, the shaft portion 210 c of the engagement member 210 comes into contact with the base plate 105, and the screw head portion 210 a is positioned at a gap below the base plate 105 by the length in the axial direction of the shaft portion 210 c.

In the connection plate 200, the shaft portion (displacement allowance portion) 210 c of the engagement member 210 enters the insertion portion 202 of the connection portion 201 and engages with the engagement portion 203, and thus, the sofas 101 and 101 adjacent to each other are connected to each other.

Here, the engagement member 210 can be inserted into the insertion portion 202 of the connection portion 201 in a state where the cushion portion 102 c is compressively deformed in the direction in which two sofas 101 and 101 adjacent to each other approach each other.

Accordingly, in the sofa system 100, in order to connect the sofas 101 and 101 adjacent to each other with the connection plate 200, as shown in FIGS. 20A and 20B, the connection member 200 rotates about the screw 206, and the shaft portion 210 c of the engagement member 210 is received into the connection portion 201. At this time, even in a state where the sofas 101 and 101 only come into contact with each other, as shown in FIG. 20B, the insertion portion 202 of the connection portion 201 interferes with the shaft portion 210 c of the engagement member 210. Accordingly, as shown in FIG. 21, the cushion portions 102 c are compressively deformed in the direction in which two sofas 101 and 101 adjacent to each other approach each other. Preferably, the cushion portions 102 c are pressed in the direction two sofas 101 and 101 adjacent to each other approach each other. Therefore, the engagement member 210 can be inserted into the engagement portion 203 through the insertion portion 202 of the connection portion 201 on the first end portion of the connection plate 200.

In addition, after the connection portion 201 of the connection plate 200 engages with the sofa 101, the pressing between sofas 101 and 101 is released. Accordingly, the cushion portions 102 c are deformed in a direction in which the cushion portions 102 c return to the original shapes by repulsive forces of the compressively deformed cushion portions 102 c. As a result, the engagement member 210 engages with the engagement recess portion 203 a of the engagement portion 203 of the connection portion 201. Accordingly, in the connection portion 201 on first end side of the connection plate 200, the engagement state with respect to the sofa 101 is maintained. In this way, two sofas 101 and 101 adjacent to each other are connected.

In addition, as shown in FIG. 20B, in order to release the connection between the two sofas 101 and 101 performed by the connection plate 200, the cushion portions 102 c which are pressed in the direction in which the two sofas 101 and 101 adjacent to each other approach each other are compressively deformed. Accordingly, the shaft portion 210 c of the engagement member 210 is displaced from the state of entering the engagement recess portion 203 a of the engagement portion 203 so as to engage with the engagement portion 203 to a position at which the shaft portion 210 c communicates with the insertion portion 202. In this state, as shown in FIG. 20A, if the connection plate 200 rotates about the connection hole 205, the shaft portion 210 c of the engagement member 210 is extracted from the insertion portion 202. In this way, it is possible to disengage the connection portion 201 on the first end portion of the connection plate 200 from the sofas 101.

Here, as shown in FIG. 17, the length in the axial direction of the shaft portion 210 c of the engagement member 210 is set so as to be greater than the thickness of the connection plate 200. Accordingly, the connection portion 201 of the connection plate 200 can engage with the shaft portion 210 c of the engagement member 210 in a state capable of being displaced in the height direction of the sofa 101.

As described above, in the sofa system 100, the sofas 101 and 101 adjacent to each other are connected by the connection plate 200. In addition, the connection portion 201 on the first end portion of the connection plate 200 can engage with and disengage from the sofa 101 in the state where the cushion portions 102 c are compressively deformed in the direction in which the two sofas 101 and 101 adjacent to each other approach each other, and the engagement state of the connection portion 201 with respect to the sofa 101 is maintained in which the compressively deformed cushion portions 102 c are deformed in the direction in which the cushion portions 102 c return to the original shapes.

Accordingly, in the case where the two sofas 101 and 101 adjacent to each other are connected to each other by the connection plate 200, it is possible to allow the connection portion 201 to engage with the sofa 101 in the state where the cushion portion 102 c is compressively deformed in the direction in which the two sofas 101 and 101 adjacent to each other approach each other. In addition, after the connection portion 201 engages with the sofa 101, the pressing between the sofas 101 and 101 is released. Accordingly, the compressively deformed cushion portions 102 c are deformed in the direction in which the cushion portions 102 c return to the original shapes, and the engagement state of the connection portion 201 with respect to the sofa 101 is maintained. Therefore, the two sofas 101 and 101 are connected to each other.

In addition, in order to release the connection between the two sofas 101 and 101, if the two sofas 101 and 101 adjacent to each other are pressed in the direction in which the sofas 101 and 101 approach each other and the cushion portion 102 c is compressively deformed, it is possible to disengage the connection portion 201 of the connection plate 200 from the sofa 101.

In this way, it is possible to easily and reliably connect the sofas 101 and 101 to each other and prevent the positional deviation of the sofa 101.

Moreover, the engagement member 210 with which the connection plate 200 engages is provided in one of the sofas 101 adjacent to each other, and the connection portion 201 includes the insertion portion 202 into which the engagement member 210 is inserted in the state where the cushion portions 102 c are compressively deformed in the direction in which the two sofas 101 and 101 adjacent to each other approach each other, and the engagement portion 203 which is formed so as to be continuous to the insertion portion 202, is further enlarged in the direction, in which the cushion portions 102 c returns to the original shapes, relative to the insertion portion 202, and with which the engagement member 210 engages.

According to this configuration, since the engagement member 210 is inserted into the insertion portion 202 in the state where the cushion portions 102 c are compressively deformed in the direction in which the two sofas 101 and 101 adjacent to each other approach each other, the connection portion 201 can engage with and disengage from one of the sofa 101.

In addition, if the compressively deformed cushion portions 102 c are deformed in the direction in which the cushion portions 102 c return to the original shapes, the engagement member 210 engages with the engagement portion 203 which is further enlarged in the direction in which the cushion portions 102 c return to the original shapes relative to the insertion portion 202. Accordingly, the engagement state with respect to one of the sofa 101 is maintained.

In addition, the connection hole 205 on the second end portion of the connection plate 200 is rotatably connected to the other of the sofas 101 which is adjacent thereof.

According to this configuration, by rotating the connection plate 200, it is possible to easily connect the two sofas 101 and 101 adjacent to each other.
